Warning
Gas Alarm Systems strongly recommends that remote
inhibit switches be key operated only, and that
access to the key should be restricted to authorised
personnel. A Gasmaster system that has been inhibited
without other safety precautions being in place may
not provide the protection for which it was designed.
Steps should be taken to ensure that all appropriate
personnel are aware when a Gasmaster system is
inhibited.
